hi..i have done as dannywonglh has put in his post earlier..but wat i'm facing is that my speed is only half of wat its supposed to be..when i do a speedtest or torrent its only getting 5Mbps meanwhile if i change back to the Thompson router i get 10Mbps..anybody got a solution for that ? and i'm not sure on how to enable the openWRT.

I have done the VLAN trunk settings as well.

i'm using the TP Link TL WR1043ND. Connection is stable but not as fast as the Thompson.
